Silver Ring

Dear Hallmark Guru,

I have in my possesion a unique ring with some age.
There is some writing / hallmarks on the inside of it and I will enclose some pictures of the ring itself but cannot seem to get a clear picture of the hallmarkes themselves.

reading from right to left it starts out with "STE (worn out area) MH " and then a pie shape with something in the middle of it or perhaps a bell shape. Any help would be greatly appreciated.

Thanks Dan
